Personnel at the circulation desk in the library aren't just there to check the library's physical materials out and back in, and to collect fines on overdue materials. They, too, are trained to address reference queries from all the patrons. They have an excellent grasp of the library's resources and have also been trained to locate information of all sorts and provide you with access to it. While these people may be swamped with a line of patrons waiting to be taken care of, they may also politely refer you to another librarian at the reference desk. They have a very tough job too!
